Question

A contractor finds that 5 gallons of paint will cover 750 sq ft of wall area. How much wall area could be covered with 15 gallons of​ paint?

Answer 1

To find out how much wall area could be covered with 15 gallons of paint, we first need to determine the area that can be covered by 1 gallon of paint.

According to the problem, 5 gallons of paint cover 750 square feet. We can calculate the coverage per gallon:

\[
\text{Coverage per gallon} = \frac{750 \text{ sq ft}}{5 \text{ gallons}} = 150 \text{ sq ft per gallon}
\]

Now, we can find out how much area can be covered by 15 gallons of paint:

\[
\text{Total coverage with 15 gallons} = 15 \text{ gallons} \times 150 \text{ sq ft per gallon} = 2250 \text{ sq ft}
\]

Therefore, 15 gallons of paint can cover **2250 square feet** of wall area.
